Review - Kinematics

Front

What is velocity?

Back

Speed in a specific direction.

Front

What equation should you choose to find the acceleration of a car that speeds up from 29 m/s to 34 m/s over a distance of 110 m?

Back

v² = v₀² + 2ad

Front

A car accelerates uniformly from rest at 3.2 m/s². What is its speed after traveling 40 m?

Back

16 m/s

Front

What happens to the velocity of a ball as it is dropped off a cliff?

Back

It increases at a uniform rate.

Front

What does negative acceleration indicate about an object's motion?

Back

The object is slowing down.

Front

Define acceleration.

Back

The rate of change of velocity of an object.

Front

What is the formula for calculating acceleration?

Back

a = (v - v₀) / t

Front

What is the difference between speed and velocity?

Back

Speed is the distance traveled per unit of time; velocity includes direction.

Front

What is uniform acceleration?

Back

Acceleration that is constant in both magnitude and direction.

Front

What is the formula for distance traveled under constant acceleration?

Back

d = v₀t + 1/2at²
